President Donald Trump plans to lower flags to half-staff to remember Americans who have died due to the coronavirus.

He announced the reflection Thursday for federal buildings and national monuments.

It came after top Democratic leaders urged Trump to fly flags at half-staff on public buildings across the country when the U.S. coronavirus death toll reaches 100,000.

House Speaker Nancy Pelosi and Senate Minority Leader Chuck Schumer made the request in a letter sent to Trump on Thursday. They say the gesture would “serve as a national expression of grief so needed by everyone in our country.”

There have been more than 94,000 COVID-19 deaths in the U.S., according to Johns Hopkins University.
